WELLINGTON P. DOLLOFF, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO FRED I.MAROY & 00., OF SAME PLACE.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 244,867, dated July 26,1881. i Application filed May 28,1881. (No model.) I

To all whom t't may concern Be it known that I, WELLINGTON P. DoL- LOFF,of Providence, in the State of Rhode.

' tion taken at right angles to the plane of the post. Fig. 2 representsa similar section taken in a plane parallel with the side of the post.

Fig. 3 represents a side elevation of the post as completely formed.Fig. 4 represents a side elevation of the u-formed post previous tobending the arms outward. Fig. 5 represents an edge elevation of thesame. Fig. 6 represents a plan view of the hinge-plate of Fig. 7represents an edge view of the same. Fig. Srepresents aplan view, andFig. 9 an edge view, of the spring.

In the drawings, A is the head of the button; B, the post, made ofsquare wire, bent as shown in Fig. 4; or the post may be cut in the formrepresented from a piece of sheet metal. The hinge-plate E of the shoeis struck up so as to form the curved bridge 0 between the twoperforations a a. The arms b b of the pest B, after beingpassed throughthe openings a a, from the back of the plate, are preferably bent inopposite directions, as shown in Figs.

2 and 3, in order to form a secure attachment to the head of the button.The spring D is made in the form of a cross orwith radiating arms dd,thus forming from a single piece of sheet metal a powerful andsufficiently pliable spring.

In putting the severalparts of the button together the ends of theu-formed post are first passed into the perforationssa a from the backof the plate E until the bend or central portion brings up against theunder side of scribed.

the bridge a. The spring D is then placed in the hollow of the shoe-capF, and the edges of the shoe-cap turned down over the edge of thehinge-plate E, thus securing the several parts firmly together. The endsof the L1- formed post may now be soldered direct to the back of thehead of the button or otherwise, the ends of the post may be turnedoutwardly by means of pliers, as represented in Fig. 3, and thensoldered to the head A, thus securing a greater bearing-surface for thepost against the back of the head A, and increasin g the strength of thesoldered joint.

When the shoe is turned, as shown in Fig. l, at right angles to thepost, the spring D presses upward against the flat surface of the lowerpart of the post, thus retaining the shoe in the position for lockingthe button into the button-hole, and when, in removing the button fromthe button-hole, the shoe is turned, as shown in Fig. 2, then thepressure of the spring D against the flat side of the post will serve toretain the shoe in that position durin g its removal from thebutton-hole, and also during its subsequent insertion therein.

.In order'to make the post B as short as practicable when a largecircular shoe is ernployed, the perforations a a and bridge e may bemade at one side of the plate E; but in case of the employment of asmall circular shoe, or of an oval shoe, the bridge 6 may be made at thecenter of the plate.

I claim as my invention- 1. In a button, the combination of the shoecapF, spring D, and hinge-plate E, provided with the perforations a a, andthe intervening curved bridge 6, with the Ll-formed post B, having itsends placed through the perforations in theplateE,substantially asdescribed.

2. In a button, the combination of the shoecap F, spring D, perforatedhinge-plate E, and LJ-formed post B, having its ends passed through theperforations a a in the plate E, and bent outwardly, substantially asde- WELLINGTON P. DOLLOFF, -Witnesses:
